To all whom it may concern:

Be it known that I, ALFRED DIEUDONN ESTIENNE, of thecity of Marseilles,France, have invented Improvements in Decorticating-Machines, (forwhichI have obtained Letters Patent in France, for fi fteen years, datedOctober1,1894,N0.229,095; in Belgium,forfif teen years,dated October12,1894,N0. 112,217; in Spain, for ten years,dated January 10,1895, No.16,523, L. 20, Fol. 445; in Italy, for fifteen years, dated December 31,1894, Vol. 73, No. 427; in Germany, for fifteen years, dated N- vember7, 1894, No. 84,738; in Argentine Republic, for ten years, dated April1, 1895, No. 1,582; in India, for fourteen years, dated December 6,1894, No. 336, and in Turkey, for

fiteen years,dated December 21,1894,N0. 277,) of Which the following isa full, clear, and exact description.

This invention relates to an improvement in the decorticating-machineforming the subject of previous Letters Patent, numbered 531,307 and549,116, respectively; and it has for its object to prevent the stalksafter being formed into stricks adhering to the revolving bed whichreeeives the impact of the beaterblades.

My improvement consists in the combination, With the beater-cylinder ofa bed-cylinder revolved at the same surface speed as the beater-cylinderand furnished With bedgrooves between which and the'beaters the tressesor stricks are nipped and scraped and of an endless series ofstripping-slats running on the bed-cylinder intermediate of the clasticbeds for, preventing the adhesion of the stricks to the bed-cylinder.

Reference is to be had to the accompanying drawing, forming part of thisspecification, which represents a cross-section of the improved machine.

According to my invention the endless apron and contact-roller of theformer ar rangement are replaced by a bed-roller 2', provided Withlongitudinal ribs each bearing a longitudinal groove L3 in its outeredge, in which a strip of indiaL-rubber or other elastic material may beinserted. The grooVes coincide With and receive the edges of the blades0 of the beater-drum a, the shafts of the drum a and roller i beinggeared together by a wheel A and pinion B, so that the drum andbed-roller revolve at the same surface speed. The stalks fed in by therollers cl 6 over the breaker-bar or anvil h are struck and broken 5 5by the beater-blades c, the strick of filaments then beingnippeclbetween the edges of the blades and the bed-grooves of roller i,into which the filaments are pressed and between which and the bladesthe filaments are continuously rubbed and scraped both on their upperand under surfaces.

In order to prevent the stricks adhering to the ribs 72 there iscombined with the bedroller 1' an endless series of stripper-bars orSlat's 4, attached to belts or chains 1, running on end pulleys orpinions t on the shaft of bed-roller 2' and on pulleys 2 'or a drum upona counter-shaft 3. The stripper bars or slats 4. are of sufficientbreadth to prevent the stricks coiling around them and may be arrangedin groups of two, as shown, the ribs t' 01: the bed-roller passingthrough the intervening spacs. By this means the stricks after beingacted on by the beater-blades are strpped from the bed-grooves of thebedroller by the succeeding pairs of slats 4.

The stripper-slats are kept clean by coming in contact With a Stationarybrush 5.

I claim 1. In a machine for decorticating ramie and other textilematerials, the combination of a beater-cylinder provided withbeater-blades,

a bed-cylinder coperating therewith and pro- Vided With grooved ribsreceiving and coinciding with an edge of the beater-blades between whichribs and the beaterblades the filaments are nipped and scraped, acountershaft, an endless series of stripper-slats rumning around thebed-cylinder and the counter-shaft, the said slats during the operationof the machine lying between the said ribs of the bed-cylinder,substantially as and for the purposes specified.

2. In a machine for decorticating ramie and other textile materials, thecombination of a bcater-cylinder provided with beater-blades, a bedcylinder 01' 1oller provdcd with grooved ribs, beds 0f elastc materal1yng in the grooves, the said bcater-cyhnder and bed-cyl= nder being s0arranged that the filaments will be nipped bctwcen the bladcs of thebeater-cyfinder and the rbs of the bccLcylinder and thereby scraped, acountenshafc, an endlcss series of stripper-sIats runnng 1o around thebed-cylinder and the countershaft, and a stationarybrash adapted toreach contact With and keep the slats clean during operation of themachine.

- The foregoing specification of my impromments in decorticatng-machincssigned by 15 me this 15th day of February, 1897.
